Abstract
The utility model discloses a pencil rotary sharpener without breaking a lead. The left side of the bottom of a sharpener frame is also provided with a hole for rotatablely sharpening a lead core, the upper part of the sharpener frame is provided with a transverse sliding chute, two lateral plates of the sliding chute are provided with symmetrical axle holes, control rods, one end of each of which is provided with a turn knob are arranged in the axle holes on the lateral plates and are in axial connection with the lateral plates, slide blocks are arranged in the sliding chute and are matched with the control rods, and blades on conical sharpening holes are fixedly connected with the slide blocks. The utility model not only can conveniently sharpen out a longer pencil point, but also can conveniently, rotatablely and quickly sharpen pencils provided with thicker lead cores; at the same time, the lead core is not easy to be broken when the pencil is rotatablely sharpened, and the utility model is novel and unique stationary.
Description
The utility model relates to a kind of pencil-knife, relates to a kind of non-breaking lead pencil volume sharpener in particular, belongs to a kind of improvement of pencil volume sharpener.
The history of the existing last 100 years of Wood-bar pencil because have that cost is low, price is low earns and write smoothly, although various propelling pencils in the market are a feast for the eyes, but Wood-bar pencil still for a long time pin do not wane.But when Wood-bar pencil uses, need be through cutter cutting pencil commonly used, the normal use that could keep pencil makes people feel very inconvenience.Though the volume sharpener of the early existing pencil of cutting fast on market, but the nib of cutting out because of volume is little, service time short, and plumbous point very easily pins blade and fractures, especially those are had than pencils of lead bullion core and just more can't use, therefore this pencil volume sharpener in stronger higher grade pupil of manipulative ability and adult few people use.
The purpose of this utility model provides a kind of pencil volume sharpener of non-breaking lead, it can not only be cut out long nib easily and can also have can roll up easily and fast equally than the pencil of lead bullion core to those and cut, simultaneously lead for retractable pencil frangibility not during roll cutting pencil.
The purpose of this utility model is achieved in that it comprises the cutting hole and the blade of knife rest, taper, it is characterized in that also having a taper volume that is communicated with cutting hole to cut the lead for retractable pencil hole in the left side of knife rest bottom; A horizontal chute is arranged at the top of knife rest, and the axis hole of symmetry is arranged on two side plates of chute; One end of control lever has a knob, and control lever places the axis hole on two side plates of chute to be dynamically connected with the side plate axle; Slide block places chute to cooperate with control lever; Blade and slide block on the taper cutting hole are affixed.
Owing to adopted such scheme, can drive slide block by control lever as required during roll cutting pencil, follow the volume of cutting hole one side in order to the adjusting blade and cut mouthful parallel moving, control volume paring blade cutting pencil wood pen holder and do not hinder lead for retractable pencil, it can not only be cut out long nib easily and can also have can roll up easily and fast equally than the pencil of lead bullion core to those and cut, simultaneously lead for retractable pencil frangibility not during roll cutting pencil.Blade mobile device mechanism volume is little, simple in structure, and whole volume sharpener volume and conventional roll cutter are more or less the same, and is a kind of novelty and the stationery that shows unique characteristics.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the front view of concrete structure of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the B-B view of Fig. 1.
Fig. 4 is another embodiment.
Fig. 5 is the A-A view of Fig. 4.
In Fig. 1-3, an injection moulding of knife rest 11 usefulness plastics is made, the cutting hole 10 that the roll cutting pencil bar of a taper is arranged on the right side of knife rest 11 bottoms, the left side of knife rest 11 bottoms also has a taper volume that is communicated with cutting hole 10 to cut lead for retractable pencil hole 9, the cone angle in lead for retractable pencil hole 9 has the cutting mouth of a cross connection less than cutting hole cone angle 0.5-15 degree on cutting hole 10 and the lead for retractable pencil hole 9.A chute 3 is arranged on the top of knife rest 11, the axis hole of horizontal symmetrical is arranged on about 3 two side plates 2,8 of chute.Be threaded made of plastic equally on the control lever 6, having with control lever at an end of control lever 6 is the manual knob 1 of one, the plug 7 of control lever 6 by the other end is inserted in the axis hole on about 3 two side plates 2,8 of chute, control lever head 7 hot melts are riveted on the right plate 8 of chute, and control lever 6 and 2,8 of side plates are dynamically connected.Slide block 5 is a cuboid, and a horizontal threaded through hole is arranged at the middle part of slide block 5, and slide block 5 places chute 3 to be threaded with control lever 6 by through hole, and slide block 5 can follow chute 3 and horizontally slip under the effect of control lever 6.Have connecting hole on the blade 4, the preceding face of slide block 5 has the connecting hole corresponding with blade 4, and blade 5 usefulness screws and slide block 5 be affixed to be made on the cutting mouth that blade is close to cutting hole 10,9.
Fig. 4 is another embodiment, in Fig. 4-5, is provided with control lever 6 at the middle part of control lever 6 and is the profile of tooth tooth 12 of one.There is laterally zygomorphic axis hole at the middle part of chute two side plates about in the of 3, and control lever 6 is inserted in the axis hole of chute side plate about in the of 3, and control lever head 7 hot melts are riveted on the chute lower plate, and control lever 6 and side plate axle up and down are dynamically connected.Have one laterally to be the tooth bar 13 of one with slide block 5 at the rear portion of slide block 5, slide block 5 places chute 3 to cooperate with slide block tooth bar 13 by profile of tooth tooth 12 with the control lever 6 of being with profile of tooth tooth 12, and slide block 5 can follow chute 3 and horizontally slip under the teeth effect on the control lever 6.
During the cutting pencil, knob 1 on the rotation control rod 6 moves to right slide block 5 in chute 3, drive blade 4 same moved further, after blade 4 is reserved the lead for retractable pencil position according to the thickness of lead core diameter, pencil is inserted in the cutting hole 10, meet the blade rotation pencil again, just the rod of pencil front end can be cut and do not hinder lead for retractable pencil, lead for retractable pencil is remained intact.By knob 1 blade 4 is moved on to the left end of knife rest 11 again, the plumbous point that the pencil front end is reamed rod inserts volume and cuts in the lead for retractable pencil hole 9, and rotation pencil makes that the lead for retractable pencil cutting is full to the brim to come gently again.Also blade 4 can be transferred to the centre position, just can equally use with common pencil volume cutter.
